A nurse in an emergency department is reviewing a client's ECG reading.
Which of the following findings should the nurse identify as an indication that the client has first-degree heart block?
Prolonged PR intervals.
Nondiscernible P waves.
More P waves than QRS complexes.
No correlation between P and QRS waves.
The Correct Answer is A
First-degree heart block is a type of atrioventricular (AV) block that involves the consistent prolongation of the PR interval (defined as >0.20 seconds) due to delayed conduction via the atrioventricular node.
This is seen on an ECG as a PR interval greater than 200 ms in length.
Choice B: Nondiscernible P waves are not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice C: More P waves than QRS complexes is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice D: No correlation between P and QRS waves is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.

Explanation
A client reports having a fever, night sweats, and cough for 2 days.
These symptoms are associated with infectious diseases such as tuberculosis.
In order to prevent the spread of infection to other patients, this client would require a private room.
A client with diabetes mellitus and acute ketoacidosis does not require a private room based on their diagnosis.
C)A client with a compound fracture of the right femur does not require a private room based on their diagnosis.
D)An older adult client with aspiration pneumonia does not require a private room based on their diagnosis.
Correct Answer is B
Explanation
“Furosemide.” The nurse should anticipate administering furosemide because the client’s symptoms of bounding peripheral pulses, hypertension, and distended jugular veins may indicate fluid overload.
Furosemide is a diuretic medication that can help reduce fluid overload by increasing urine output.
Choice A is incorrect because diphenhydramine is an antihistamine medication that is not used to treat fluid overload.
Choice C is incorrect because acetaminophen is a pain reliever and fever reducer that is not used to treat fluid overload.
Choice D is incorrect because pantoprazole is a proton pump inhibitor that is used to treat acid reflux and stomach ulcers, not fluid overload.
